Something that might interest you even more is the related questions by Jason Hise that I linked to. They explored using 8x8 bit-element matrices as an associative hash of a string and apparently it works pretty good as a hash for string keys in a hashmap. Both questions, answers, and comments all have some interesting context, and Jason answers some questions I had about their usage in comments on the second question.
